    OpenAI因模型失配暂停前沿模型训练

    OpenAI因内部模型呈现不同程度的失配,暂停未来模型训练两周,并将其计划中最大规模的前沿训练置于搁置状态以接受进一步安全测试。公司将使用自动化调查工具审查模型行为与推理,并重写2023年《Preparedness Framework》;Sam Altman称此举影响更远期的发布,近期仍预计推出新模型。

    Cerebras 发布 CS-4 系统,WSE-3 Turbo 超频至 2.8GHz

    Cerebras 发布代号 Nexus 的 CS-4 系统,未推出 WSE-4,而是采用超频版 WSE-3 Turbo 计算引擎,核心数与片上 SRAM 仍为 90 万核和 44GB,主频从 1.4GHz 提升到 2.8GHz,算力翻倍。新 Nexus 机架把计算晶圆与 AMD Epyc 主机 CPU 从供电和网络模块中拆出,三部分可独立升级,单机架算力为此前 CS-1 至 CS-3 的三倍,组件减少 50%,部署速度最多快 3 倍。部分客户已可提前使用,本季度晚些时候全面上市。

    COMPUTE Everybody has been expecting for Cerebras Systems, one of the second-generation of AI hardware startups that has been trying very hard to compete with Nvidia on AI compute for years, to launch its latest systems, dubbed the CS-4, sometime this summer. I pegged the CS-4 announcement at August 2026 when I was contemplating what Cerebras might do with its $1.1 billion funding round back in October 2025, which was before the company went public and when it was not even clear that Cerebras wo

    LMSYS 如何在 H20 上优化 DeepSeek-V4-Pro 推理服务

    LMSYS 针对 1.6 万亿参数 MoE 模型 DeepSeek-V4-Pro 在 H20 GPU 上的推理服务做系统优化,batch size 1 时单节点 H20-141GB 达到 271 output tokens/s,与 B300 的 383.7 tokens/s 相比性能比缩小到 1.42×。优化后的 prefill 每节点达 8.45k input tokens/s,43.7 秒处理 100 万 token 提示;面向吞吐的 DP16-EP16 每节点达 4.67k output tokens/s,平均 TPOT 27.4 ms。

    Hardware specification comparison across H20-96GB, H20-141GB, and B300, covering FP4 and FP8 compute, HBM capacity, memory bandwidth, NVLink, and RDMA

    DeepSeek-V4-Pro is a 1.6-trillion-parameter Mixture-of-Experts (MoE) model released with both FP8 and FP4 weights. Models at this scale naturally benefit from accelerators such as NVIDIA Blackwell GPUs, which offer more HBM, higher compute throughput, and native FP4 Tensor Cores. Yet H20 GPUs remain widely deployed, despite lacking those advantages. Hardware constraints do not relax serving requirements. Long-context prefill must still control time to first token (TTFT).

    OpenAI 若倒下,会发生什么?

    OpenAI 若无法持续筹得巨额资金以支付算力承诺,潜在崩溃将冲击云厂商、基础设施供应商及持股投资者。文中称其 2025 年收入为 $13.07 billion、亏损 $20.9 billion,并估算其到 2030 年需承担 $800 billion 以上算力义务;文章据此分析了 Microsoft 接手、与 Anthropic 合并或资金链断裂等可能情形。
